The Vanishing Alarm Clock has been built by many manufacturers over the years but the original ones were invented by Willmann and Conradi c. 1904. Versions by Thayer, Brema, Abbott’s, and others have been created through the years. Probably the company that popularized the effect the most in the USA was Petrie-Lewis c. 1932 and their version is shown here. It is a beautiful version that works very smoothly.
This is a a wonderful effect that looks as amazing today as it did 70+ years ago. Even in the extreme conditions of a Speed Demo where everything if focused on the props it looks pretty convincing, so imagine how good it would look in your parlor or stage act or as a show piece in your collection 🙂
